Troubleshooting:
Malfunctions Possible Causes Solutions
All LEDs don’t work
1. The power supply did not connect to power
grid. Power on
2. No electricity due to short-circuit of external
power supply.
Remove the malfunction caused by short-circuit, power on
again.
3. The wires of strips connect to power supply
output reversely.
Check the connecting and ensure the wires are connected
correctly.
Part of LEDs don’t work
1. Part of power supplies do not have output. Check the power supply system.
2. Part of wires of strips have malfunction.
3. Particular modules connected reversely. Correct connection
Brightness of LEDs is
weak or uneven
1. Overloaded power supply; Replace it with higher power supply
2. The power loss of power circuit is huge or the
power loss of each circuit existing big
difference.
Ensure working voltage of strips is within±5%V of rated
voltage.
1. Shorten the length of wires between the first strip and
power supply or replaced with wires with bigger diameter;
2. Ensure the cascading qty of string is less than or equal to
the allowed maximum cascading qty, and each strip
cascading qty is well-balanced.)
3. Exceed in qty of strips in series Lessen the cascading qty for strip and ensure the qty for each
electrical circuit is within the maximum cascading qty.
LEDs are blinking 1. Poor contacted in the joints. Find out and tackle malfunction immediately.
2. Failures in power supply. Replace power supply.
